Two civilians were seriously wounded and a Togolese UN peacekeeper killed Sunday after their convoy triggered a mine to explode in central Mali.

The attack came on a day Canadian Defense Minister Harjit Sajjan held talks with Malian authorities on the deployment of 600 Canadian peacekeepers to the West African nation.

An African military official told the AFP news agency that they have lost a Togolese peacekeeper among those injured as a result of the blast. The total number of those injured remains unknown. Military officials ruled it as a planned attack in Mali’s Mopti region.

UN said the attack took place in a city not far from Douentza. At least 11,000 UN troops are stationed in the country with more than 30 troops killed this year.

French troops intervened in Mali after Jihadist groups laid siege on the former colony. The UN is hoping that Canadian helicopters can be deployed in the region after the Dutch withdraw next year.
